Background / History
The Sage of Six Paths created Gyuki and the other Tailed Beasts by dividing the Ten-Tails’ chakra. Hashirama Senju later captured and distributed the beasts among the major shinobi villages. In Kumogakure, Gyuki went on destructive rampages before Killer B became his Jinchuriki; the two eventually became close partners 384 593 675 762.
During the Cloud–Sand Allied Forces’ battle against Saiki Yuu, Gyuki fought alongside Killer B and the Two-Tails, Matatabi. Yuu’s attacks caused Gyuki intense pain, and Gyuki lost tails while shielding Matatabi from Shukaku’s Tailed Beast Bombs. After Yuu defeated them, Gyuki agreed to escort Shukaku and Matatabi to Konoha. Yuu healed his wounds and regrew his severed tails before they departed 640 642 662 671 673.
Gyuki remained in Konoha when Killer B was ransomed and returned home. Their separation distressed them both, though Yuu offered Gyuki leave to visit if he worked for him. Years later, Gyuki chose to stay in Konoha and received permission to visit Kumogakure regularly 761 762 1299.

Personality
Gyuki is proud but cautious when he recognizes a threat. He identified Yuu’s Six Paths Power before the other beasts understood it, warned Killer B repeatedly, and ultimately submitted rather than risk their lives 577 593 656 672.
His bond with Killer B has made him gentler toward the other Tailed Beasts. He worries about B’s safety, fights beside him despite his fear of Yuu, and chooses separation when it gives B a chance to return home 595 640 761 762.
